Error description
• Check if the own station/relay station/connected station is running
normally.
• Check if there is a problem with the cable connection between the
own station and the connected station.
• Increase the TCP resend timer value.
• Increase the time reserved for the communication process.
• For a Basic model QCPU, High Performance model QCPU,
Process CPU, or Redundant CPU, use Time reserved for
communication process (SD315).
• For a Universal model QCPU, configure the service processing
setting in "PLC System" under "PLC Parameter".
• Execute the request from another station again.
• Correct the send message size of the request source.
• In the Station No.<->IP information setting, set the IP addresses
for the CC-Link IE Controller Network, CC-Link IE Field Network,
MELSECNET/H, and MELSECNET/10 relay communication target
devices.
• Increase the request interval.
• Decrease the number of request nodes.
• Wait for a response to the previous request before sending the
next request.
• Correct the timeout value.
• Correct the request details.
• Correct the network number or PC number.
• Correct the request details.
• Cancel the current request.
• Specify the channel number from 1 to 8.
• Change the channel number.
• Perform communications again after the current communications
are completed.
• Correct the network number or PC number.
• Check the programmable controller CPU operation.
• Perform the open process.
• Check the operation of the connected device.
• After sending a close request (FIN) from the connected device to
the E71, perform the open process again and wait for 500ms or
more.
• Perform the open process and send the request.
• Follow the procedure below.
(1) Check if each module is properly mounted on the base unit.
(2) Check if the operating environment of the Ethernet module
conforms to the general specifications of the CPU module.
(3) Check if the power capacity is sufficient.
(4) Check if the hardware is normal according to the manual for
each module.
If the actions above do not solve the problem, please consult your
local Mitsubishi representative.
